    Component and Connector Views in Practice
    (Software Engineering und Software Management 2018, 2018) Bertram, Vincent; Maoz, Shahar; Ringert, Jan Oliver; Rumpe, Bernhard; von Wenckstern, Michael
    We have presented an experience report of applying Component and Connector (C&C) view verification with an industrial partner, at the MoDELS 2017 conference. C&C views are a means for formal yet intuitive structural specification of C&C models. We report on our experience how C&C views and their verification help to address challenges of traceability and evolution in automotive industry. We analyzed the development process at Daimler AG and evaluated our C&C views verification tool on five Simulink models with more than 7700 subsystems in total and C&C views created for 183 textual requirements provided by Daimler AG. We describe our experience in detail and discuss a list of lessons learned, including, e.g., a missing abstraction concept in C&C models and C&C views that we have identified and added to the views language and tool, that engineers can create graphical C&C views quite easily, and how verification algorithms scale on real-size industry models. Furthermore, we report on the non-negligible technical effort needed to translate Simulink block diagrams to C&C models. We make all materials mentioned and used in our experience electronically available for inspection and further research.

    Infrastructure to use OCL for runtime structural compatibility checks of simulink models
    (Modellierung 2016, 2016) Bertram, Vincent; Manhart, Peter; Plotnikov, Dimitri; Rumpe, Bernhard; Schulze, Christoph; Wenckstern, Michael Von
    Functional development of embedded software systems in the automotive industry is mostly done using models consisting of highly adjustable and potentially reusable components. A basic pre-requisite for reuse is structural compatibility of available component versions and variants. Since each vendor in the automotive domain uses its own toolchain with corresponding models, an unified modeling notation is needed. For this reason based on a detailed feature analysis of wellestablished and commonly used modeling languages, a meta-model has been derived that allows checking structural compatibility, even between heterogeneous modeling languages.
